1) The minor repairs in the equipment did not work according to the planned maintenance. The headaches, the pains of the feet, the exhaustion of the feet, the exhaustion of the maintenance workers, and the endless emergence of equipment problems, the cycle of reciprocation, the equipment is getting better and worse.
2) Spare parts preparation is not timely and quality is not guaranteed. If the spare parts are not prepared in time, the consumable parts of the equipment will not be allowed to continue to be used according to the regulations, but the spare parts that need to be replaced cannot be replaced, so they must continue to use it to deal with and make do with it. In the end, it was really impossible to deal with the forced parking, and the repair time was longer and the labor was more laborious. The quality of the spare parts is also a big problem. Some of the factories have not been strictly inspected and the requirements are not strict, and they have been replaced during the inspection of the equipment. The time is not long and bad. Some of them only run a few classes and are broken. This is a factor that causes frequent maintenance.
3) The quality of maintenance inspection is not guaranteed. This problem is divided into two aspects. On the one hand, some of the maintenance workers have a strong sense of responsibility and sloppy thinking; on the other hand, most of the current selection of young workers are more, the cultural knowledge is not high, and the general technical level is relatively low. Some equipment construction and maintenance specifications are still not clear, and the quality of maintenance is not known. Thus increasing the business knowledge, technical education has become universal metallurgical front a very important job.
4) The post operator maintenance equipment is not elaborate enough.
The above four questions reflect why some companies have low equipment operating rates. Therefore, strengthening enterprise management and strengthening the technical education of employees can improve the equipment operation rate and complete the production plan issued by the state. Here, we must pay attention to and prevent the completion of the task in order to complete the task, so that the equipment can be used for long-term disease operation, resulting in the phenomenon of not killing and not grinding, and it is not allowed to complete the operation rate by this method.
The operating rate is a percentage. The larger value indicates that the grinding operation time is long, and the actual driving time is short.
Calculation formula μ=(the total working hours of the grinding machine/the total number of calendar hours in the specified time)×100%
For example, a mill grinding system in a total of 650 hours in April, its operating rate is:
μ=[650÷(30×24)]×100%=90.27%
